Calculating the jet quenching parameter.
It is observed that q can be given a model-independent, nonperturbative, quantum field theoretic definition in terms of the short-distance behavior of a particular lightlike Wilson loop, and a strong-coupling calculation of q is obtained in hot N=4 supersymmetric QCD.
The Condensed matter physics of QCD
Important progress in understanding the behavior of hadronic matter at high density has been achieved recently, by adapting the techniques of condensed matter theory. At asymptotic densities, the…
Gauge/String Duality, Hot QCD and Heavy Ion Collisions
Over the last decade, both experimental and theoretical advances have brought the need for strong coupling techniques in the analysis of deconfined QCD matter and heavy ion collisions to the…
Wilson loops in heavy ion collisions and their calculation in AdS/CFT
Expectation values of Wilson loops define the nonperturbative properties of the hot medium produced in heavy ion collisions that arise in the analysis of both radiative parton energy loss and…
An AdS/CFT Calculation of Screening in a Hot Wind
One of the challenges in relating experimental measurements of the suppression in the number of J/\psi mesons produced in heavy ion collisions to lattice QCD calculations is that whereas the lattice…
Anti-de sitter/conformal-field-theory calculation of screening in a hot wind.
This work presents the first rigorous nonperturbative calculation of the consequences of a wind velocity v on the screening length L(s) for a heavy quark-antiquark pair in hot N=4 supersymmetric QCD with f(v) only mildly dependent on v and the wind direction.

Event-by-Event Fluctuations in Heavy Ion Collisions and the QCD Critical Point
The event-by-event fluctuations of suitably chosen observables in heavy ion collisions at CERN SPS, BNL RHIC, and CERN LHC can tell us about the thermodynamic properties of the hadronic system at…
